I am attempting to display three figures, side by side in a table. I've placed the table inside the figure* environment to make the table the full width of the page, however the corresponding caption then overlaps the table. I can hackishly fix this by appending an empty row to the bottom of the table and making it sufficiently large, but I was wondering if there is a more elegant solution.
Here is a model working example
\documentclass[nohyper,nofonts]{tufte-handout}
\usepackage{pgfplots}
\usepackage{lipsum}
\newcommand{\emptyfig}{\begin{tikzpicture}%
\begin{axis}[width=\textwidth/3,height=\textwidth/3]%
%\addplot[black] coordinates { (0,0) (1,1) };
\end{axis}%
\end{tikzpicture}}
\begin{document}
\begin{figure*}
\begin{tabular}{ccc}
\emptyfig & \emptyfig & \emptyfig \\
Hi & Hi & Hi
\end{tabular}
\caption{This is an overlapping caption}
\end{figure*}
\end{document}
and the corresponding output.
